With their candidate on the losing end of the Pennsylvania primary, lead supporters of Barack Obama rallied their troops in at the Water Works restaurant in Philadelphia, telling them they should be proud of their efforts.

"We should be so proud of what we have done," said U.S. Rep. Patrick Murphy, D-Bucks. "There were 10,000 of you out knocking on doors, phonebanking."

And U.S. Representative Chaka Fattah said that when the Democratic convention is held in Denver, delegates won by Obama in Pennsylvania will help him secure the nomination.

"There are going to be delegates who were elected here in Philadelphia and throughout the state that are going to put him over the top," Fattah said.

Obama's Pennsylvania spokesman Sean Smith said it was too early to say how the delegates would break. They are awarded based on a complicated system that weighs the total vote and the vote within districts where Democratic turnout is strong.

Sen. Robert P. CaseyJr.said that whether or not they voted for his this time, Pennsylvanians will be ready to back Obama when he's running against Republican John McCain in November.

"They saw his heart, they saw his values, they saw the kind of leader he is," Casey said.
